It features a modified bottoming chamfer, 3 right-hand spiral flutes with a 10-degree helix angle, and a TiCN coating over a powdered metal substrate. The H3 thread limit and 2B class of fit deliver consistent tolerance control in production and maintenance applications. The spiral flute geometry pulls chips up and out of the hole, making this tap well suited for blind-hole tapping in tough alloys. Overall length is 2.756 inches with a thread length of 0.866 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in stainless steel, hardened steel, titanium, and high-nickel alloys — materials that demand a rigid, wear-resistant cutting tool. It is sized for 10-32 UNF threads, a fine-thread pitch common in fastener applications across aerospace, defense, medical device, and general precision machining. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a standard plug or taper tap. It is run on CNC machining centers, drill presses, and tapping machines by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral flute design with 10-degree helix angle evacuates chips upward from blind holes\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves wear resistance and reduces built-up edge in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction provides uniform carbide distribution and consistent tool life\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading near the base of a blind hole\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit with 2B class of fit for controlled tolerance in production threading\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread and right-hand flute direction for standard CNC and manual tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for material applications including stainless steel, hardened steel, titanium, and high-nickel alloys.

Power down or stop spindle rotation completely before loading or removing the tap from the holder. Use a tap holder sized for the 0.194-inch shank diameter. Do not exceed the recommended speed and feed for the specific workpiece material, and always use a cutting fluid appropriate for the alloy being tapped.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel, Hardened Steel, Titanium, High-Nickel Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.756 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.866 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.194 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.976 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.152 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 313NI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.021 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1709508\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737521652018,"sku":"1709508","price":78.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2ee6e713832d885bec8b3aba4b54119.jpg?v=1788789718","url":"https:\/\/voomisupply.com\/products\/osg-1709508-spiral-flute-tap-10-32-unf-3-flutes-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
